Hi, sorry for my English, I'm kind of new of this archetipe and wanna try the deck at the gp Bilbao next week, i tested for 2 month and I think is really strong in this meta.
My problems are 22 or 23 lands (prefer 23 in testing) and more nexus/muta over zhafir void.
Find a right sideboard is really hard for me, this is probably the configuration i have in mind for it:
4 relic of the progenitus
4 spatial contorntion
2 ratchet bomb
2 gut shot
2 damping sphere??
Not sure of this 3 slot
Prefer the relic because needed in uw and BGx match up, but is very slow against Phoenix and shadow, and bad with chalice...
If i play leyline need some space for some card against this 2 mu
